If the target destination has a waypoint, we enforce that the request is coming from that waypoint. Otherwise, the request is rejected.
If there is no waypoint, ztunnel will enforce RBAC policies against the request.

If all checks pass, ztunnel will open a connection to the target. This will spoof the source IP (from `Forwarded` for waypoints, or the incoming IP otherwise).
